In the thirtieth century, a corrupt galactic federation, with Earth at it's center, drugs it's billions of citizens into placid submission. A rebel named Roj Blake, who once tried to orginize a resistance group to overthrow this regime, was caught and divested of his memories. But Blake's revolutionary spirit is revived when he witnesses a mass slaughter by police that is covered up by the Federation officals. He escapes exile onboard a prison spaceship and, together with a loveable band of outlaws, takes over a vacant alien space cruiser of awesome drive capability. Naming their new ship "The Liberator", Blake and his group travel the milky way to seek any oppertunity to undermine the evil federation.
